Dens Invaginatus
Pronunciation: denz in-VAJ-ih-NAY-tus
A developmental malformation in which the enamel organ folds inward into the dental papilla during tooth formation, creating a canal or cavity within the tooth crown or root.
Full Definition
Dens invaginatus (also historically termed 'dens in dente') is a tooth development anomaly resulting from infolding of the enamel organ before mineralisation, producing an invagination that extends into the crown and, in severe cases, the root. The Oehlers classification (Types I–III) grades severity and is commonly referenced in case reports. In editorial contexts, 'dens invaginatus' is the preferred current term; 'dens in dente' is an older synonym and should be glossed or replaced per house style. The Latin plural is 'dens invaginati', though 'dens invaginatus cases' is acceptable in English text. Editors should ensure the Oehlers type is correctly cited when referenced.
Usage
Usage note: 'Dens invaginatus' is the preferred modern term; 'dens in dente' may be retained in historical context or quotation only. Italicise as a Latin term on first use per most style guides.
